Live on Solana mainnet · day 42

The proof,
read from the chain.

How Meridian works, as it happens on Solana mainnet: a rule on a wallet, the slice saved within seconds, a Pyth price the program checks, a receipt anyone can open, measured at 7 and 30 days, the Plans that match it, and the launches on Meridian Curve whose fees fund the matches.

Start saving Save once

Meridian invests a slice of your wallet’s USDC inflows. Payers never open Meridian; pausing is a token-program revoke that Meridian cannot prevent. Ten percent by default, one signature to start.

Paying a team? Pay them in stock — their first share arrives with a receipt that says why.

What happens when money lands

A payment arrives. A rule runs. A receipt prints.

01A payer sends USDC to a normal address
02The balance rises above the watermark; Meridian notices
03begin_sweep — the program computes the slice from on-chain state
04The route — Jupiter, as a top-level instruction the program watches
05finish_sweep — the fill is checked against Pyth, or everything reverts
06The receipt is written; the rest of the money never moved

The last sweep, replayed from its receipt.Open the receipt

You’re already getting paid. Investing shouldn’t take another decision.

What a stock could never do before

Eight things a brokerage share never did, each one on Solana today.

01It can be paidA stock arrives as a payment: pay a person or a whole team in the S&P 500, to their own wallet, with no brokerage account on either side.Pay someone in stock 02It obeys a rule on an addressA standing instruction on the account money already lands in. Ten percent by default; a signature to start; a revoke to stop.The latest sweep 03It remembers why it arrivedEvery receipt carries the reason, from whom, at which price, and whether it is still held at 7 and 30 days.How receipts work 04It vests, from anyone to anyoneA grant is stock bought now that releases on a schedule: the retention instrument public companies use, in any listed company, from any organisation.Grants that vest 05It arrives before the opening bell50% of arrivals here settled while the NYSE was shut. When no price can be verified, at a weekend, an arrival waits in the wallet instead of converting on a guess.The clock on the floor 06It can be givenA first share can be sent to someone who has never held one. They claim it into their own wallet, and a receipt says who gave it and why.Give a first share 07It proves it was keptKeep-rate is measured on chain at 7 and 30 days from raw units, by anyone. It cannot be faked.100% kept at 7 days 08It prices a launch that pays saversA token launched on Meridian Curve is priced in a stock on Meteora. Every buy pays in the stock, and the savers' share of every trading fee goes to a Plan that adds it to automatic saves.Meridian Curve

The evidence

A rule on income is the only version that has ever worked at scale.

401(k) participation among new hires, after automatic enrollmentMadrian & Shea, 2001

after86%

Every consumer version since needs a US bank and a US brokerage. On Solana the wallet is the paycheck account for everyone paid in stablecoins, and nobody had put a rule on it.

Before you ask

The things a savings product should say first.

Not our custody

Your USDC and your stock sit in token accounts you own. Meridian holds a rule and writes receipts; it never holds an asset across a slot.

The issuer can move these tokens

xStocks are tracker certificates issued by Backed, with a permanent delegate and a pause authority. Self-custody here means not our custody. Not offered to US persons.

Dividends are reinvested, not paid

They arrive as a mint-level multiplier that rebases balances. Meridian never shows an expected income.

Net, not gross

The rule sees the net increase of your USDC account since the last sweep. Money spent before it is saved is not counted.

Savings-grade, not stable

Equities fall as well as rise. Meridian competes for the position that sits idle, never for your cash.

The public record

Everything that has settled, and how much of it is still held.

Open the ledger. Every stub is an account anyone can read, anchored to a transaction that already happened. Launch fees that fund savings, through Meteora: the launchpad.

Say yes once. Every payment saves itself.

Ten percent by default. Pausing is a revoke. Every receipt is an account anyone can open.
